Introduced: unknown Terminated: unknown |
| Notes: |
This is a calculator with some scientific functions, such as powers,
roots, the constant π, reciprocals and percentages. Looks like an
extended version of the TRIUMPH 80C S.
The calculator has memory, and the special "Σ"-slider, when set to Σ will automatically add a calculation’s result to the calculator’s memory when the = key is pressed. Pressing the Mout key twice will clear the memory. I couldn’t figure out what the "ALG - BUS"-slider does. Just like the TRIUMPH 81C, every key has its own spring. |
